Hertel C.402.0725 Jobber Drill Bit 7.25 Mm Hss

Product Description

The HERTEL C.402.0725 is a high speed steel jobber-length drill bit designed for general-purpose hole-making in a wide range of materials. It features a 7.25 mm (0.2854 inch) diameter, a standard 118-degree split-free point angle, and a black oxide finish that provides mild corrosion resistance and reduces friction during cutting. With a straight-cylindrical shank and right-hand spiral flute geometry, this bit is compatible with standard drill chucks and drilling machines. It is suited for machinists, maintenance technicians, and fabricators who need a reliable, stock-size jobber drill for everyday production or repair work.

This drill bit is intended for general-purpose drilling in mild steel, aluminum, plastics, and similar workpiece materials. At 108 mm overall length with a 75 mm flute length, it fits within the standard jobber-length range, making it appropriate for bench drill presses, CNC machining centers, and hand-held drilling equipment where a straight shank is required. It falls within the 7.00 mm to 8.00 mm drill bit size range and carries UNSPSC code 23241634, which is useful for procurement and inventory classification in industrial supply systems.

Key Features

• 7.25 mm (0.2854 inch) diameter with a 118-degree standard point angle for general-purpose entry
• High speed steel construction provides hardness and heat resistance for metal drilling applications
• Black oxide coating reduces surface friction and provides mild corrosion resistance
• Right-hand, two-flute spiral design promotes efficient chip evacuation
• Straight-cylindrical shank fits standard three-jaw drill chucks without adapters
• Jobber-length geometry at 108 mm OAL balances reach and rigidity for common drilling tasks

Compatibility

Designed as a general-purpose jobber drill bit for use in standard drill chucks accepting straight-cylindrical shanks; fits within the 7.00 mm to 8.00 mm drill diameter range.

Installation Notes

This drill bit is installed and operated by machinists, maintenance technicians, and fabricators using drill presses, lathes, or hand-held drilling equipment. Secure the straight shank fully in a properly tightened three-jaw chuck before operation. Always ensure the workpiece is clamped or fixtured securely to prevent rotation or movement during drilling. Follow applicable shop safety procedures and machine guarding requirements when operating drilling equipment.
